How to debug (or trace) EventLoop callbacks?

[vovkapoc]

Hello everybody! Sorry for the stupid question, but I'm new to EventLoop/Fiber/async in php. Please tell me how to debug the main EventLoop? For example, I get callback ids that are currently active using EventLoop::getIdentifiers(), using var_dump(EventLoop::getDriver()) I see the types of all fiber IDs. But how to understand by fiber ID which callback is tied to it?
It's interesting because I use some libraries from amphp and as a result I see 3 fiber's that I didn't create and which for some reason do not close on their own at the end of the program's cycle. I want to understand which callbacks are connected to these ids.

Sorry for my bad English, I from Ukraine!

P. S. EventLoop use libuv as primary driver

Callback IDs aren't tied to fibers. You can use REVOLT_DRIVER_DEBUG_TRACE to use the TracingDriver to record additional debugging information. dump can be used to get info about the creation traces of still enabled callbacks:

event-loop/src/EventLoop/Driver/TracingDriver.php

Line 192 in 358572c

public function dump(): string
